Application filed September 11, 1912.

To all whom it may concern:

Be it known that I, DAVID D. GooD,a citizen of the United States, residing in Landis township, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Automatic Train-Stopping Devices, ofwhich the following is a specification, reference being had therein to the accompanying drawing.

My invention has relation to automatic train stopping devices of that class wherein the stopping of a locomotive, trolley car, or other vehicle running on rails, is automatically effected by means of a stop, obstruction, or tripping device located on or adjacent to the rail and co-acting with mechanism on the vehicle to stop the latter independently, that is without volition, of the engineer, motorman, or other operator on the vehicle.

My invention has for its object, the provision of a portable stop, obstruction, or trippingdevice of novel construction, adapted tooperate the stopping mechanism on the vehicle and which can be readily carriedto any point of the track where there is a rail joint and easily and speedily attached to the. rail, and which, after its function has been performed, can be easily and speedily detached and removed for subsequent use.

My invention'consists in the novel constructions, combinations and arrangements of parts hereinafter described.

Referring to the accompanying drawings illustrating my invention in which:

Figure 1 is a side elevation of a portion of a locomotive and part of a railroad track having my improvements applied to the locomotive and to one ofthe rails of the track. Fig. 2 is a perspective view of a portion of two meeting rails of a railroad track having a joint connection of the usual character and having my improved portable stop, obstruction, or tripping device applied in operative position and showing also a portion of the stopping mechanism carried by the locomotive. Fig. 3 is a horizontal sectional view of a portion of two rails and a rail joint connection and having my improved portable stop, obstruction, or tripping device applied'thereto.

Specification of Letters Patent.

Serial No. 719,830.

The portable stop, obstruction, or tripp ng device which constitutes my invention will be hereinafter, for the sake of brevity, designated simply as the stop, it being understood that this word is intended to designate that part which while it is portable and attachable to and detachable fromthe rail, is and remains stationary and really constitutes a; stop, while its function of stopping the locomotive is being performed.

The stop is composed of the top plate 1,

Patented Jan. 9, 1917 Q of triangular form, the central vertical plate 2, having a web at its outer edge that extends abovethe plate 1, a part of the plate 2, also extending above plate 1, these uprail 5, and at one side of the central plate 2,-

and at right angles thereto, is arranged a vertical plate 6, that is of the same vertical height as the web of the rail 5, and bears wardly extending parts of plate 2, constiv against the outer side of, the web, fitting snugly between the head and the base of the rail, the plate 6 'beingconnected to the vertical depending flange 4, by an angular portion 7, the upper surface of which forms a shoulder that bears against the lower side of the head of the rail 5. The inner part ofthe lower edge of the central plate 2, is cut away to conform to the shape of the base of the rail to prevent downward displacement, and the plate 6 is formed with a projection 8, that fits into the groove 9 on the inner side of the fish plate 10, the latter being attached to the rails by bolts 11, in the usual manner.

The stop constructed as above described can be very readily carried in the hand and easily and speedily placed in position by laying it against the side of a rail adjacent the end of a fish plate and then sliding it along until the projection 8, has entered the groove in the fish plate and the side of the central plate 2 is in contact with theend of the fish plate, at which position the stop 'proaching train to be stopped and preferably on the outside of the right hand rail of the track.

Upon a part 12 of the truck or frame work of the locomotive which moves parallel to and at a fixed distance from the track, there is attached a hanger or support of suitable form, that shown in the drawings being composed of a vertical arm 13, a horizontal arm 14:, and side webs 15, the horizontal arm being formed with slots 1 1 to receive bolts or screws by which it is secured to the part 12, of the locomotive, the slots 1 1 permitting adjustment of the hanger or support, in a horizontal direction.

A valve casing 16 is attached to the outer side of the vertical arm 13, of the hanger or support by clamps 13, having threaded ends which pass through holes in the vertical arm 13, and receive nuts which hold the clamps in position, the clamps embracing vertical tubes 17 and 18, that extend upw wardly itrom the valve casing 16 and are formed integral with the casing or may be formed separately from the casing and screwed into it, as may be desired, the upper ends of these tubes 17 and 18, being corrugated to receive air hose connections 19, 20.

' The valve casing 16, is of substantially rectangular form and has a vertically arranged, rotary, conical, valve 21, carrying on its upper protruding end a nut 22, and having a stem 23 on its lower end that extends through a bushing 24:, on the lower side of the casing and carries a curved lever 25, which is so located and of such length that it will contact with the vertical lug 3, of the stop and turn the valve 21,

when the locomotive reaches the point at which the stop is located on the track.

Within the cab of the locomotive or other point within convenient reach of the engineer, there is located an air cylinder 30, containing a piston, 30' which is attached to a piston rod 31, that extends through one end of the cylinder 30, and is attached to the sliding gate of a gate valve 33, the latter being arranged on the steam pipe 34:, leading from the usual throttle valve of the engme to the steam cylinders and constituting, in effect, as will be presently described,

an automatic auxiliary throttle valve.

The end of the air cylinder 30, is connected by the hose connection 19, with the tube 17 on valve casing 16, and the air cylinder has ports 35, in its side leading from the interior of the cylinder to the open air, these ports 35, being so located that the piston 30 will just have passed them as the movement of the piston and gate of the gate valve 33, has efiected the complete closing of the gate valve, thus permitting of the free escape of the air from behind. the piston,

immediately after and practically simultaneously with the shutting ofi of the steam to the cylinders by the closing of the gate ver 37 is pivotally mounted on the base 36,

at 39, the extension 38, of lever being forked and its forked arms embracing the piston rod 31, and the latter having a crosspin 40, that is engaged by the forked arms of extension 38, when the lever is raised, this movement of the lever serving to open the gate in the gate valve 33, and simultaneously force the piston 30" back to its original position in the air cylinder 30, lever 37 then dropping back to normal position by its own Weight.

The hose connection 20, leads from the tube 18, to the air brake line, it being understood that the air cylinder as above described is adapted to be used where the 10- comotive is equipped with a vacuum air brake system in which the brakes are set or put on by the escape of compressed air which holds the brakes in unset position until it is allowed to escape.

Operation: WVhen, for any reason, a locomotive or train is stopped and it is believed that there is danger that another locomotive or train will follow or approach it on the same track, a member of the train crew carries one of the portable stops to a point a suflicient distance along the track toinsure against danger of collision by the moving train by reason of any impetus it may have after its brakes are set and its steam turned OE, and there aflixes the stop to the track in the manner and position hereinbefore described. When the oncoming locomotive reaches the stop the lever 25, will strike the vertical lug 3 of the stopand the valve 21 will be turned so as to open communication between pipes 19-20, through the valve 21. The air from the brake cylinder will then flow into the air cylinder 30, by Way of the hose connections 19, 20, the tubes 17, 18 and the valve casing 16, and will immediately force the piston 30 in a direction toward the gate valve, closing the latter and shutting off the steam. Simultaneously with the shutting off of the steam the pOrts 35 will be opened by the movement of the piston and the compressed air will then freely escape and, as is well understood, will immediately set or put on the brakes and the locomotive will thereby be stopped,'as it will be seen, automatically and independently or without volition of the engineer. To start the locomotive after it has been automatically stopped, as above described, it is only necessary to turn the lever 25, back to its original position so as to close valve 21, and then raise the lever 37, and this movement of After the lever 37, will open the gate valve or auxiliary throttle valve 33, and force the piston 30, back to its original position, thus leaving all parts ready for subsequent operation. portable stop has performed its function it is removed from its position on the track and put back on the locomotive or train from which it was taken, tocbe used again When, and as often, asmay'be required.
